Environmental Changes & Water/Carbon Cycles

• environmental changes cause the distribution of organisms to change
• 3 types environmental changes

  • availability of water
  • temperature
  • atmospheric gases
• environmental changes are caused by

  • seasonal factors
  • geographic factors
  • human interaction
• the water cycle

  A) condensation

  B) precipitation

  C) evaporation

  D) surface runoff

  E) groundwater

  
• process of water cycle

  • water starts off in sea then evaporated from energy in the sun
  • warm water vapour is carried upwards and goes higher up til it cools and condenses to form clouds
  • this falls as precipitation
  • this then drains back into the sea by surface run off or groundwater
• the carbon cycle

  
• environmental changes that could affect distribution of species

  • climate change
  • deforestation
  • pollution
• • climate change - changes in temperature alter the habitats of species
  • deforestation - loss of habitats decline of species population
  • pollution - effects water sources, disrupts ecosystems and harm organisms
